2016 AUDI A8 inflation pressure

Driving safety
-Never leave your vehicle unattended espe­
cially with the rear lid left open. A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out . Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Never let children play in or around the vehi­
cle.
- Never let passengers ride in the luggage compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.
- Air circulation helps to reduce window fog­
ging . Stale air escapes to the outside
through vents in the trim panel, on the left
side of the luggage compartment. Be sure
to keep these slots free and open.
- The tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B·pillar. The tire pressure label lists the recommended cold
tire inflation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man­
ufactured. For recommended tire pressures
for normal load conditions, please see chap­
ter ¢
page 247.
Tie-downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items .
Use the tie-dow ns to secure your cargo properly
¢ page 135, Loading the luggage compartment .
In a coll ision, the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury . Items in the vehicle possess energy which
vary with vehicle speed and the weight of the item. Vehicle speed is the most significant factor.
For example, in a frontal collision at a speed of
30 mph (48 km/h), the forces acting on a 10 -lb
(4 .5 kg) object are about 20 times the normal
136
weight of the item. This means that the weight
of the item would suddenly be about
200 lbs. (90 kg) . You can imagine the injuries
that a 200 lbs. (90 kg) item flying freely through
the passenger compartment could cause in a col­
lision like th is.
A WARNING
Weak, damaged or improper straps used to
secure items to tie-downs can fail during hard
braking or in a collision and cause serious per­
sonal injury.
- Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help prevent items from shifting or flying forward as dan­
gerous missiles.
- Never attach a child safety seat tether strap
to a tie-down.

A WARNING
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of an accident.
-Only use tires that are more than 6 years old when abso-
244
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

tor
Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer or authorized repair facility

Wheels
-Always make sure that the to­tal load being transported -
including the weight of a trail ­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­ late the total weight of the pas­
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be overload­ ed .
Steps for Determining Correct
Load Limit
1 . Locate the statement "THE
COMBINED WEIGHT O F OCCU ­
PANTS AND CARGO SHO ULD
NEV ER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
¢ page 246, fig . 207 .
2. Determine the combined
weight of the driver and pas­sengers that will be riding in
your vehicle .
250
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 246, fig . 207 .
4. The resu lting fig ure equals the
available amount of cargo and luggage load capacity . For ex­
ample, if the "XXX" amount
equals
1400 lbs. and there will
be five
150 l bs . passengers in
your vehic le, the amount of
available cargo and luggage load capac ity is
650 lbs .
(1400-750 (S x 150) = 650
lbs.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle .
That weight may not safely ex­
ceed the available cargo and luggage load capacity calcu lat­
ed in Step 4.
6 . If your vehicle will be towing a
trailer, load from your trailer
w ill be transferred to your ve­
hic le. Consu lt th is manua l to
determine how this reduces
the available cargo and lug­
gage load capacity of yo ur vehi-
cle.

Snow chains not only improve the driving in win­
ter road conditions, but also the broking.
Use of snow cha ins is o nly pe rm itted with certain
r im/t ire combinations due to tec hni cal reasons.
Check with an authorized Audi dealer or author­
ized repair faci lity to see if yo u may use snow
cha ins .
The snow c ha ins must have
low-profile lin ks and
m ust not be thicker than 0 .4 inch (10.S mm), in ­
cluding the lock.
You mus t remove the c hains whe n driving on
roads that are
free of snow. When roads are free
of snow, snow c hains can impair handling and
damage the tires, and the chains wi ll quickly be
destroyed .
_& WARNING
Using inco rrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
cont rol, which inc reases the risk of an acc i­
dent .
{CT) Note
-Snow cha ins can damage the rims/wheel
covers* if the chains come into d irect con­
tact with them . Remove the wheel cove rs*
first. Use coated snow chai ns.
- Using snow chains that add more than 0.4
inch (10.5 mm) of he ight can severely dam­
age the wheel hous ings and other vehicle
components.
- Do not i nstall and use snow chai ns if there is
a malfunct ion in the adaptive air suspen­
s io n, because the vehicle he igh t will be very
l ow. If you drive wi th snow ch ains anyw ay,
the wheel ho usings and other vehi cle com ­
ponen ts can be severely damaged .

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra ­
tio tires . These ti res have been tho roughly tested
252
and been sele cted specifica lly for your mode l for
their superb performance, road fee l and hand ling
u nder a var iety of dr iv ing cond it ions. Ask your au ­
thori zed Audi dea ler fo r more details.
The low aspect rat io o f these tires is indica ted by
a n umera l of
55 or less in the tire's size designa­
t ion . The n umera l represents the ratio of the
tire's sidewall height in relation to its tread width
expressed in percentage. Convent iona l tires have
a height/width ratio of 60 or more .
The performance of low-aspect-ratio tires is par­
t ic ularly sensitive to improper inflation pres ­
sure.
It is the refore important that low aspect
ratio tire s are inflated to the specified pressure
and that the inflation pressur e is regularly
checked and maintained . T ir e pressures should
b e c hec ked at l east on ce a month and alway s
befor e a long trip
¢ page 246.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more eas i­
l y by impact with potholes, curbs, gullies or
ridges on the road, particularly if the tire is un­
derinflated.
In orde r to mi nimi ze the occur rence of impact
dam age to the tires of yo ur vehicle, we recom ­
mend tha t you observe the following preca u­
tions:
- Always ma intain recommended i nflation pres­
sures. Check yo ur tir e pressure eve ry 2,0 00
m iles (3,000 km) and add air if necessary .
- Dr ive ca refully on roads w ith potholes, deep
gullies o r ridges. The impac t from dr iv ing
through or over such obstacles can damage
your tires. Impact with a curb may a lso ca use
damage to your ti res.
-After any impact, immediate ly inspect you r
tires or have them inspected by the nearest au­
thorized A udi dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 mi les (3,000 km)
for damage and wear. Damage is not always
easy to see . Damage can lead to loss of air and
underinflation, wh ich could eventually cause
tire fa ilure . If you be lieve that a tire may have .,.

_& WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinf lat ­

Tire pressure monitoring system
U) General notes
Applies to: vehicles with tire pressure monito ring system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure fo r those tir es) .
As an added safety feature, your vehicle has been
equipped with a t ire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­
ly under-inflated . Accord ingly, when the low tire
p ressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib ility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is comb ined w ith the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain cont inuous ly
illuminated. This sequence will continue upon
254
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illum inated,
the system may not be able to detect or s ignal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
i nstallation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears
Applies to: vehicles with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig . 209 Instrument cl uste r: indicator light with me ssage
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread c ircumfer­
ence and v ibration characteristics of the individu­
al tires.
If the pressure changes in one or more
ti res, this is ind icated in the instrument cluster
display with an indicator light
[I] and a message.
If only one tire is affected, the locat ion of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle ¢

tor ing system only monitors the tire pressure you
have stored . Refer to the t ire pressure label for ..,.
